Volumetric Spectral Diagnostics of Particle Laden Plumes

The primary technology developed under this program will be an advanced flowfield diagnostic system to provide comprehensive reactive scalar measurements in high speed, turbulent reacting flows. Such a diagnostic technique is needed to support computational modeling advancements that are critical to support Army force protection requirements against tactical and theater ballistic missile threats.This will be accomplished through the development of a plenoptic imaging system capable of capturing velocity and scalar fluctuation statistics in high speed missile base flow-like environments.Such measurements are required to advance current state-of-the-art models for turbulencechemistry interactions.The unique feature of this diagnostic approach is the fact that a complete 3D representation of the scalar fields may be obtained with a single instrument setup.This is in contrast to current reacting flow diagnostic procedures that require the instrument to be moved laterally to populate a 3D matrix of collection planes or points.As a result, current diagnostic procedures must be applied over many realizations of a flame experiment to populate the 3D data collection matrix.The simultaneous measurement of the entire 3D scalar field using plenoptic technology developed under this program will be ground breaking.
